[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a high-hardness spherical crown-shaped head.

[0025] Embodiment 1

[0026] Reference Figure 1-3 , a high-hardness spherical cap head, comprising a first head 1 and a second head 2, the first head 1 and the second head 2 are symmetrically arranged, the first head 1 and the second head 2 are rotatably connected on the opposite sides through a sealed bearing with a rotating block, one end of a rotating rod 6 is fixedly connected to the corresponding rotating block, and the rotating rod 6 is convenient to rotate, the first head 1 and the second head 2 are both made of iron-silicon alloy, so that the first head 1 and the second head 2 have higher strength, the first head 1 and the second head 2 are rotatably arranged on the inner middle part of the first head 1 and the second head 2, and a connecting block 5 is fixedly arranged on one end of the rotating rod 6, and a plurality of extension blocks 7 are sequentially arranged on the side close to the two connecting blocks 5, and a threaded rod 4 and an internal threaded pipe 3 are arranged between the extension blocks 7 on both sides, and a wedge-shaped groove is opened on the side of the connecting blocks 5 and the extension blocks 7 on both sides close to the corresponding first head 1 and the second head 2, and a wedge-shaped block 8 is clamped inside the plurality of wedge-shaped grooves, and the plurality of wedge-shaped blocks 8 are respectively fixedly connected to the corresponding extension blocks 7, the threaded rod 4 and the internal threaded pipe 3.

[0027] Embodiment 2

[0028] Reference Figure 1-3 The outer walls of the plurality of connecting blocks 5 and the extension blocks 7 are provided with a limiting mechanism for limiting the movement of the wedge-shaped block 8. The limiting mechanism includes a fixed ring 9 and a movable ring 10. The plurality of fixed rings 9 are respectively fixedly sleeved on the middle ends of the corresponding connecting blocks 5 and the extension blocks 7. The plurality of movable rings 10 are slidably sleeved on the outer sides of the corresponding wedge-shaped grooves. Slide rods 11 are movably sleeved inside the two ends of the fixed ring 9. One end of the slide rod 11 is fixedly connected to the corresponding movable ring 10. A stopper 13 is fixedly provided on the end of the slide rod 11 away from the corresponding movable ring 10. The stopper 13 conflicts with the side of the corresponding fixed ring 9 away from the movable ring 10 to prevent the slide rod 11 from slipping out of the fixed ring 9 as much as possible. A spring 12 is movably sleeved on the rod wall of the slide rod 11. The two ends of the spring 12 are respectively fixedly connected to the corresponding fixed ring 9 and the movable ring 10 to facilitate the resetting of the movable ring 10.

[0029] When the utility model is in use, the movable ring 10 is pulled toward the side close to the fixed ring 9, so that the movable ring 10 is moved away from the outer side of the corresponding wedge-shaped groove, and the wedge-shaped block 8 can be pulled out of the wedge-shaped groove, so that the number of extension blocks 7 can be conveniently increased or decreased, and the spacing between the first head 1 and the second head 2 can be adjusted. Since the spacing between the first head 1 and the second head 2 can be adjusted, it can adapt to the installation of pipelines of different lengths. At the same time, due to the adoption of a multi-section combination design, there is no need to process longer-sized threaded rods 4 and internally threaded pipes 3, which can reduce the difficulty of production. After adjusting the installation size, the first head 1 and the second head 2 are sealed at both ends of the pipeline, and then the rotating blocks on both sides are rotated in reverse, so that the threaded rod 4 and the internally threaded pipe 3 can be threadedly connected, and the installation of the first head 1 and the second head 2 and the pipeline can be completed.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
